WILLIAM STANLEY BENFIELD, OF SAN FRANCISCO, CALIFORNIA.

VALVE.-

Application filed- January 8", 192;; Serial No. 435,891.

To all whom it may concern:

Be it known. that I, PENFIELD, a citizen of the United States, and a resident of San Francisco, county of San Francisco, and State of Qalifornia, have inventeda new and1useful Valve,,ofwhich the following is a specification The-invention relates-to an improved valve which is especially adapted: for controlling;

the discharge of gasoline and the like from the tanks of motor tank-trucks such as are used in supplying gasoline service stations, stores, etc.

The primary object of the invention is to provide a valve of the" character described,

which will be quick acting and provide for an expeditious discharge and filling action, which will be positive, reliable and leakproof and which will be easy to operate, durable and subject to a ready and easy dlS- assembling for the purpose of renewing parts which have become Worn or damaged.

Another object of, the invention is to pr'ovide a valve of the character described which will be small, compact, and simple as to construction and comparatively inexpenslve.

A further object is to provide avalve of the character described which will permit of a more rapid and reliable filling or discharging action and thereby provide for an ap- A preciable saving in vtime required in the various fillingoperations in which the valve is used.

Another object isto provide in a valve of the character described means for support-'. ing a receptacle in position to receive the' will be set forth at length in the following,

description wherein I shalloutline infull that form of the invention which I have selected for illustration in thedrawingsaccompanying and forming a part of the pres ent specification. In said drawings I'have shown one form of the construction of my invention but it is to be understood that I do not limit myself to such form, since the WILLIAM STANLEY invention as expressed in the claims may be embodied in a plurality of forms.

Referring to the drawing Figure l is a sectional view partly in elevation of the valve of my invention ;.v

Figure 2 is an enlarged fragmentary sec valve, showing the locking means for looking the valve closed.

In the present embodiment of the inven tion shown in the accompanying drawings, there is provided a body casting (1) shaped tional view of a modified construction of they p i to provide a valve casing 7 (2), discharge spout a connection nipple (4). The nipple 1) is internally threaded and. providedwith a nut-like hexagonallportion (4') exteriorly thereof. The nipple 1s connected with the tank, not 'shown, in the usual manner.

The rear face of the casing (2) is formed with ascrew threaded opening (5) through which a cylindrical valve seat member (6) is inserted in the assembling of the valve.

The inner end of the seat member (61) is re duced and extends through a reduced portion of the casing. The reductionsproviding.

abutting shoulders (8) and (9) are on the seat member and easing respectively. A gasket (10) is mounted between the shoulcers.

The reduced end (7) is formed withabeveled seat (11) for a circular disk valve (12) which valve has a stem (13) reciprocally supported in an inwardly projecting boss (14) carried by the member (6) The outer endof the member'(6) is closed by a wall (15) which wall carries the boss (14:), The lower side of the seatniember (6) is .provided with a large opening (16 )j leading, into the spout.

The stem (13) extends through the boss which boss is hollowed out as at (17). An

expansion spring (18) surrounds thestern with the hollow portion of the boss and abuts a pin (19) on the stem and the boss,

respectively, so as to at all times exert a force acting to close the valve. A plug (20) is turned in the opening (5) and conceals the member (6) and spring and retains these parts in place. The stem extends through a boss (21) on the centre of the plug and projects outwardly a slight distance. By re -moving the plug, the member (6) and valve may be readily and easily removed so as to replace worn parts or inspect the said parts. Pivoted upon an ear (22) situated on the upper side of the casing is an operating lever (23) of substantially an L-shape, there being provided a handle portion (24:) and an operating portion Anintermediate part of the'portion (25) abuts the outer end of the valve stem. The lower end of this por tion (25) is formed as a book (26), arranged to support a bucket or other receptacle in position to receive the discharge from the spout. A suitable stop lug (27) is provided on the casing to properly limit theinward movement of the portion (25) of the lever. An apertured car (28) is provided on the plug and extends outwardly beyond and close to the portion of the lever. By

- inserting a suitable pin not shown, through the aperture in the ear when the valve is opened, the part (25) of the lever will abut the pin and be held against movement whereby the valve will be held open.

As shown in Figure 2 the outer end of the stem may be apertured as at (29) so that the hasp of a pad lock (31) may be inserted therethrough when thevalve is closed and the valve locked thus in closed position. 0 pera tion.

When the handle of the lever is depressed the valve is opened against the action of the spring but opens quickly to the leverage action provided and bv reason of the large valve openings and passages through the valve casing and spout, a. maximum discharge flow results. As soon as pressure is relieved from the handle by the operator the sufiicient liquid has flowed into the receptacle to provide the necessary weight to effect a rocking of the lever and an opening of the valve, the operator may release the handle and the valve will be maintained in open position. This relieves the operator of the necessity of holding the valve handle open throughout the entire filling operation and expedites the operation as a whole.

The present type of valves used for tanktrucks are comparatively slow in action and are not leak-proof. It is the main object of the invention to provide a time and gasoline saving valve which may be repaired much more easily and cheaply than the ordinary valve and will be more efiicientgenerally.

I claim:

1. A valve of the character described embodying in its construction a casing having an opening at one side thereof, an annular seat member withdrawable through said opening, a removable plug closing said opening, a discharge spout extending from the casing, said seat member having an opening therein registering with the spout, a valve extending through the seat memberand plug, a lever pivoted to the casing and having one portion thereof abutting the outer end of the stem, a hook portion on the lower end ofsaid lever, and a spring arranged to resist the opening movement of the valve, and means.for locking the valve in closed position.

2. In a valve of the character described, a casing, a discharge spout extending from 'the casing, an opening in one side of the casing, said opening being of substantially the same size as the inside of the casing, a valve seat member having a boss extending in wardly of the opening and formed as an integral part of the seat member, a valve seat on the inner end of said member, a valve said seat, said valvehaving a stem extending through the boss and a plug for closing the opening in the side of the casing having an opening to receive the end of the valve stem, a spring in said boss for holding the valve upon its seat and means on the outside of the casing for unseatini the valve, substantially as and for the purpose described.
